These are in cpukit/score/src/mutex.c on the master but not 4.11 as I
recall.
Are you sure you are building against a compiled master? Maybe there is a
remnant
of another build left laying around.
By any chance, did you forget to install or install to a different prefix?

I don't see any wrapper around the file at all in the Makefile.am. It
should be compiled
all the time.

I was concerned that you were missing the -B option. But I see you have it.

When you have working code to check, -Os can be beneficial. Depending on
the application,
it may not result in much difference in speed anyway. Fewer instructions is
often just as
beneficial as other optimizations. This could get you another 10% in size.
